We are actively working to minimize carbon emissions across our operations, optimize resource efficiency, and promote the use of durable, long-lasting materials that contribute to energy savings and lower emissions in high-temperature processes.
Want to know more about our Supplier Code of Conduct?
In an age of globalization and growing competitive pressure, it is important for a company that operates internationally to have consistent and uniform criteria on which to base its activities. In an continuous effort to maintain high standards in regards to human rights, workers rights and the environment, we have stipulated our principles and our expectations of how suppliers should act in our Code of Conduct.
Want to know more about our carbon footprint?
As climate concerns intensify globally, companies operating in energy- and resource-intensive industries must take responsibility for understanding and managing their environmental impact. At HASLE Refractories, we are committed to transparency in our carbon footprint reporting, providing insight into both our company-wide greenhouse gas emissions and product-level footprint estimates. This approach supports data-driven dialogue with customers and partners as we work together toward more sustainable solutions.
Advancing Sustainable Solutions
Through close collaboration with customers, suppliers, and industry partners, HASLE Refractories drives innovation in high-performance refractory materials that enable more sustainable and efficient industrial processes. From castables and precast elements to gunning mixes, our products are engineered to perform under demanding conditions—supporting long service life, easier maintenance, and optimized process performance across industries. Additionally, our solutions support the transition to alternative fuels, enabling cement and other industries to adopt more sustainable production methods.
Designed for Durability
Our castables, gunning mixes, and precast elements are engineered for long service life, reducing the need for frequent replacements and lowering resource consumption over time. Key features such as optimized grain size distribution, dense material matrices, and the use of high-purity virgin raw materials ensure mechanical strength, thermal stability, and consistent performance in extreme environments.
Enabling sustainable fuel conversion
HASLE solutions are highly resistant to chemical attack from corrosive species released during the combustion of alternative fuels such as waste, tires, and biomass. Smooth surfaces reduce coating formation and material build-up, helping maintain process stability, reduce downtime, and support optimized combustion across high-temperature processes.
Tailored Precast Solutions to maximize process efficiency
Our precast offerings, such as the Modular Lining Systems are engineered for critical equipment zones. These solutions enable fast installation, customized and multi-layered lining designs with optimized thermal properties, and very smooth surfaces, enhancing energy and process efficiency in cyclones, bull noses, furnaces, and other critical zones.
Pushing cyclone efficiency
The Ceramic Vortex Finder (CVF) is engineered to maintain high separation efficiency in cyclones, even under demanding conditions with high alternative fuel (AF) use. In the lowest cyclone stages at cement plant, the CVF helps reduce main fan electricity consumption by 2–4% and fuel use by 1–2%, compared to operations without dip tube. These efficiency gains contribute to CO₂ emission reductions, supporting a more sustainable production process.
Environmental Responsibility
While our own production has a relatively limited environmental footprint, we are committed to continuously improving the sustainability of our operations. Our focus areas include energy efficiency, resource optimization, waste reduction, and water conservation.
We have made tangible progress in reducing electricity consumption, thanks to ongoing efficiency measures and process improvements. From 2022 to 2024, our electricity use dropped by approximately 21.7%, and our energy intensity fell from 58 kWh to 48 kWh per tonne produced—reflecting upgrades such as LED lighting and investments in more energy-efficient equipment as well as product-mix changes.
At the same time, we have however seen a rise in LPG consumption in our dyr-out furnaces, which are used in our precast manufacturing process. This is linked to increased production volumes of precast elements and a shift in product mix requiring higher prefiring temperatures.
To minimize raw material loss, we use dust extraction systems in our dry castable mixing process, which recirculate collected particles directly back into the mixer. In addition, we implement water conservation practices in our precast production, where mixer cleaning water is collected and reused multiple times.
We also apply circular principles in our material handling. Castable materials that have exceeded their shelf life are repurposed into new formulations, particularly for insulating or secondary applications—extending material value and reducing waste.
Together, these initiatives demonstrate our commitment to environmental responsibility throughout our operations, as we work to align high product performance with sustainable production practices.
“With the increasing urbanization in many parts of the world, the future will bring a much larger consumption of cement. As an old, family-owned company, we feel a responsibility to contribute to a sustainable future for the cement industry.”
– Michael Bladt, CEO
Empowering people
At HASLE Refractories, our employees are our most valuable resource. Their expertise and commitment are essential to delivering the high-performance solutions our customers rely on. We strive to create a work environment that fosters safety, well-being, and long-term professional growth.
HASLE Refractories primarily employs staff on permanent contracts, ensuring stability and strong mutual commitment within our workforce. As of 2025, we have a team of 34 employees, with the majority based at our HQ and production site on Bornholm, Denmark. We also maintain an international presence, with 6 employees in India and 3 in Thailand, primarily supporting technical services and sales.
Health & Safety
Workplace safety is a fundamental value at HASLE. We are committed to ensuring that every employee can perform their work safely and return home unharmed. We operate under Denmark’s robust occupational health and safety regulations, and our internal safety culture reinforces these standards with clear procedures, open communication, and shared responsibility.
We are proud to report zero recorded work-related injuries in both 2023 and 2024, following two minor incidents in 2022. Our aim is continuous improvement—supported by active risk management, frequent reviews, and employee involvement in shaping safe working practices.
Training & Development
At HASLE Refractories, we view learning as a continuous process that evolves with our business. Our approach to training emphasizes a broad and practical skill-building framework across all functions.
We provide a variety of learning opportunities—including mandatory certifications (such as forklift training), peer-to-peer knowledge sharing, and role-specific workshops. New employees go through structured induction training to ensure a strong start, while ongoing development is supported through targeted sessions based on job needs.
In late 2023, the company implemented a new ERP system, Microsoft Dynamics 365 Business Central. All relevant staff participated in tailored training to ensure a smooth transition and improved process efficiency. Employees also engage in external conferences and seminars, gaining exposure to developments in areas such as artificial intelligence, digitalization, and industry best practices.
By combining practical, hands-on learning with exposure to broader trends, we aim to equip our workforce with the tools they need to adapt, perform, and contribute to long-term success.
A structured approach to sustainability reporting
We are proud to have published our first dedicated Sustainability Report, highlighting our approach across three key areas: environmental impact, social responsibility, and governance (ESG).
As part of our commitment to transparency and continuous improvement, we align our reporting with recognized frameworks, including the Greenhouse Gas (GHG) Protocol and emerging European sustainability standards.
Our reporting is based on EFRAG’s December 2024 draft of the Voluntary Sustainability Reporting Standard for non-listed micro, small, and medium enterprises (VSME). It includes key disclosures and metrics from the Basic Module—specifically Disclosures B1 and B2 and Basic Metrics B3 to B11. Additional data points, such as Scope 3 GHG emissions, are also included to provide a broader view of our environmental footprint.
